It's looking pretty rad so far, mate. I'm really liking the lighting in the overworld areas - the light being focused on the center of the screen during night really adds to the game's unique feel. As well I'm a big fan of the colorful graphics in general - they really make the game world feel vibrant and fun.

I do, however, think that the starters could use a little bit of work - the grass starter in particular. Its sprite looks a tad awkward - a different pose might help alleviate that a little, though. I also think the overworld sprites of the starters are a little odd looking as well, it almost seems as if they're meant to only face forward - which is really odd.

In any case, mate, good luck and I'm looking forward to playing the upcoming demo.
